MySQL Error: Table doesn't exist

Hi guys,

I'm trying to install CMS builder but I keep getting the following error:
MySQL Error: Table 'Winterbourne.cmsb__accesslist' doesn't exist

I've tried several times now but getting the same error no matter what I put in the fields. I've checked in the hosting control panel that the MySQL details are correct and cross referenced what details are used in our other installs. I've also tried renaming the files .htaccess.disabled etc. The directory name is cmsb/

Any ideas?
